StarWind Virtual SAN® Deployment in AWS EC2

Introduction to StarWind Virtual SAN for Hyper-V

StarWind Virtual SAN® is a native Windows hypervisor-centric hardware-less VM storage solution. It creates a fully fault-tolerant and high performing storage pool built for the virtualization workloads by mirroring the existing server’s storage and RAM between the participating storage cluster nodes. The mirrored storage resources are then connected to all cluster nodes and treated just as a local storage by all hypervisors and clustered applications. High Availability (HA) is achieved by providing multipath access to all storage nodes. StarWind Virtual SAN® delivers supreme performance compared to any dedicated SAN solution since it runs locally on the hypervisor and all I/O is processed by local RAM, SSD cache, and disks. This way it never gets bottlenecked by storage fabric.

The proper Virtual Private Cloud (VPC) configuration is a key to successfully realize Microsoft Failover Cluster instances on AWS.
There are two possible ways to deploy StarWind instances in AWS:

  • Two StarWind instances within the same VPC but in different Availability Zones using routing tables;
  • Two StarWind instances in different VPCs using a peering connection to communicate.

Windows Failover Clustering requires Active Directory (AD) as an orchestrator. AD DC (Active Directory Domain Controller) can be either configured as on-premises DC (Domain Controller) with VPN connections to AWS StarWind Instances or/and the virtual instance in AWS EC2 with optional replication to the on-premises domain controller using built-in active directory replication. AWS AD DC best practices can be found by following this link.

Configuring Networks in AWS EC2

1. Select a region for use in AWS EC2.
2. Open AWS Management Console and navigate to VPC option in Networking & Content Delivery section.
3. Click on the Create VPC button.

4. Go to VPC with Public and Private Subnets tab and click Select.

5. Specify IP configuration for VPC. Click on Create VPC button.

NOTE:
 All corresponding subnets must be located within the same Availability Zone.
6. Create one more VPC in the different region with subnets configured.
7. To create Peering Connections between VPC in different regions, Navigate to VPC dashboard and click on the Peering Connections tab.

8. In the Create Peering Connection window, specify Peering connection name tag, VPC (Requester), Region, VPC (Accepter).

9. Navigate to Peering Connection on the different region and accept the connection by clicking Accept Request.

10.  To add an additional Route for VPC connection, navigate to the Route Tables tab and click Edit on each VPC. 


11. Click Add another route and specify public and private subnets from partner peering connection. Repeat the same operation on other VPC in the Route Tables.

12. To allow RDP and iSCSI connections to the StarWind instances, all TCP or custom TCP rules must be configured in security groups. It is possible to either allow only 3389 (RDP port) and 3260 (iSCSI port) for security groups or allow all inbound/outbound TCP.  To customize the settings according to the company’s security policy, click Edit in the Security Group tab.

The configuration is ready for the deployment of StarWind instances and configuring HA devices with Failover Clustering.
To configure 2 StarWind instances in one VPC, please follow the sane process.
NOTE: StarWind virtual instances should be configured between 2 different Availability Zones and communication is allowed by routing tables.

Configuring StarWind EC2 Instances

NOTE: Make sure that a domain controller is set up and that configured servers are joined to the domain.
1. Install Failover Clustering, Multipath I/O features on both servers. That can be done through Server Manager (the Add Roles and Features menu item).
2. Configure network interfaces on each node making sure that Synchronization and iSCSI/StarWind Heartbeat interfaces are in different subnets. In this document, 192.168.10.x/192.168.12.x subnet is used for iSCSI/StarWind Heartbeat traffic, while 192.168.11.x/192.168.13.x subnet is used for the Synchronization traffic.
NOTE: In order to allow iSCSI Initiators to discover all StarWind Virtual SAN interfaces, StarWind configuration file (StarWind.cfg) should be changed after stopping StarWind Service on the node where it will be edited.
Locate StarWind Virtual SAN configuration file (the default path is: C:\Program Files\StarWind Software\StarWind\StarWind.cfg ) and open it via Wordpad as Administrator.
Find the <iScsiDiscoveryListInterfaces value=”0”/> string and change the value from 0 to 1 (should look as follows: <iScsiDiscoveryListInterfaces value=”1”/>). Save the changes and exit Wordpad. Once StarWind.cfg is changed and saved, StarWind service can be started.
3. On cluster nodes, open MPIO manager: Start->Administrative Tools->MPIO.
4. Navigate to the Discover Multi-Paths tab.
5. Select the Add support for iSCSI devices checkbox and click Add.
